Density of Continental & Oceanic Crust Pre-Lab Handout

Density of Continental & Oceanic Crust Pre-Lab

Define the following words:

Lithosphere: ­­­­­­­­­­­­­­­­­­­­­­-_______________________________________________________

Density: -­___________________________________________________________

Questions: -

What kind of rock is continental crust made of? (Use the ERST map) ___________

What kind of rock is oceanic crust made of? (Use the ERST map) ­­­­­­______________

Granite: - ­_________________________Basalt: - __________________________

Hint: Granite has LARGE crystals and Basalt has small crystals.

Hypothesis: -

_______________________________________________________________________

Record the Data by finding the volume with triple beam balance

                                                Density = mass/ grams

	Mass (grams)	Volume (cm3)	Density (g/cm3)
Basalt
Granite

Which crust had large density continental or oceanic? __________________________

Conclusion

Was your hypothesis supported or rejected? What did you learn? What would you do different I you would have to do this experiment again?
